Amegilla cingulata, Bombus haemorrhoidalis, Halictus propinquus, Lipotriches fulvinerva, Nomia crassipes and Megachile binghami were recorded for the first time from the state. The DNA barcode sequences of Ceratina hieroglyphica, Halictus propinquus, Nomia westwoodi, Lipotriches fulvinerva, Ceylalictus punjabensis, Coelioxys decipiens, Megachile binghami and Andrena aegyptiaca were registered for the first time in GenBank.
